Can I make an ionic liquid (dissolved salt without water) by combining zinc sulfate and glycerin? I've been using 1 M $\ce{ZnSO4}$ as my electrolyte in supercapacitor study. Works very well up to electro potential of 1.8 V (before it plates out). Would like to push electro potential closer to 3 V. Any precautions?

    $\begingroup$ I wouldn't expect zinc sulfate to be very soluble in glycerin. // Also half cell potential for aqueous solution wouldn't be exactly the same in a different solvent, but a change past 3V is probably a stretch. I don't know if any table of half-cell reactions in glycerine exists. $\endgroup$ – MaxW Apr 29 at 18:22
